GAS Plasma Voltage Dependent Switches Switching GAS DISCHARGE TUBEs

The LT Series is a 2-terminal bi-directional, voltage triggered switch is designed for ignition circuits used in high pressure HID lighting. Switching voltages for the devices are fixed depending on the part number selected. The GAS plasma trigger technology offers very fast switching speeds, resulting in significantly better di/dt values when compared to silicon based SIDAC devices. Due to the high switching voltage of the devices, step-up transformer sizes and specifications can be reduced saving cost, size and weight.

Features
• RoHS compliant
• Ceramic chamber for ultimate reliability.
• Very high switching speed once switching voltage has been reached, resulting in high di/dt to be generated enabling the best performance to be extracted from ignition transformers.
• Tape and reel to EIA 481-1

Applications
• For switching stored electrical energy (such as capacitive DISCHARGE) at predetermined voltages.
• Designed for ignition circuits used in high pressure HID lighting.

Features
● Small Size Design EIA 1812 4.5×3.2×2.7mm
● Current Handling Capability 1,000A @ 8/20 μs
● Low Capacitance and Insertion Loss
● Fast Responseand Long Service Life
● Reliable to Protect Electrostatic Surge
● Moisture sensitivity level：Level 1

GreenTUBE™ SL1122A Series Hybrid GAS Plasma Arresters

The SL1122 series Hybrid features a high performance Alpha GAS Plasma TUBE in conjunction with a high speed Silicon Avalanche Diode ( SAD ). These devices are matched so that High speed pulses are initially clamped by the SAD, then as the current rises, the transient energy is switched through the GAS TUBE. The Hybrid offers high levels of performance on fast rising transients in the domain of 100V/µS to 10 KV/µS, so eliminates the dv/dt switching delay normally exhibited by standard GDT’s. These devices are extremely robust and are able to divert a 10,000Amp pulse without destruction, so are ideal for central office ( telephone exchange ) protection.

FEATURES
• RoHs Compliant
• Excellent response to fast rising transients.
• Flat response up to 10KV/µS.
• 10KA surge capability tested with 8/20µS pulse as defined by IEC 61000-4-5
• SAD ensures short circuit failure mode in the event of severe transient overload.
• Thermal failsafe.

Applications:
• MDF protection
• Alarm panels.
• ADSL equipment.
• XDSL equipment.
• General Telecom Equipment

Description:
Designed for interfacing between MOS, or other low−voltage circuitry, and the anode of GAS DISCHARGE display panels, these monolithic high−voltage bipolar integrated circuits dramatically reduce the number of discrete components required. The NTE2025 is used with multiplexed GAS DISCHARGE display panels. The driver contains appropriate level shifting, signal amplification, output off state voltage bias, and 70mA output current sourcing for the sequential addressing of display panel anodes. The inputs inmclude pull−down resistors for direct connection to open drain PMOS logic.

The NTE2031 is a seven channel digit (anode) driver in a 16–Lead DIP type package specifically designed to be used with high–voltage, GAS–DISCHARGE numeric displays. This device requires a low logic level to turn the drivers on with a low input current requirement of any 300µA typically, and is compatible with popular MOS chips.

Features:
• High Breakdown Voltage: –55V Typ
• Low Input Current for MOS Compatibility
• Operable from Either Positive or Negative Supply Voltages
• Input Clamp Diodes for DC Restoration
• Internal Pull–Down Resistors

Description:
The NTE2026 is a monolithic high–voltage bipolar integrated circuit which dramatically reduces the number of discrete components required to link MOS, or other low–voltage circuitry, with the anodes of GAS–DISCHARGE display panels.
This device contains six drivers. Each driver has appropriate level shifting, signal amplification, output off–state voltage bias, and 40mA output current sourcing for sequential addressing of display panel anodes. The inputs include pull–down resistors for direct connection to open–drain PMOS logic.
The NTE2026 can be used in a wide variety of low– to high–voltage applications. High reliability, small size, ease of installation, and low cost make this device an ideal choice for many applications.
